A new Structured ALE solver is recently added into LS-DYNA. It targets to solve ALE problems with structured mesh. It supports all parallel versions of LS-DYNA, i.e., SMP, MPP and MPP Hybrid. The new solver generates structured ALE mesh automatically. The elements do not ...
New inflator models for the automotive air bag are developed for the pyrotechnic and hybrid inflation modes. Several propellant examples including Sodium azide(NaN3), Azodicarbonamide(C2H4N4O2), and Guanidine nitrate(CH6N4O3) are designed for users. To control the gas compositions into the airbag ...
Cohesive element approach is a promising way to simulate crack propagation. Commonly used cohesive laws include bilinear law, trapezoidal law and exponential law. However, research has found that when exponential cohesive law is unloading or reloading, the traction curve cannot remain continuous when ...
Coupling of Particle Blast Method (PBM) with Discrete Element Method for buried mine blast simulationThis paper presents two meshless methods: particles blast method (PBM) and discrete element method (DEM). Particle blast method (PBM) is intend ...
